Abstract
A hand-held crimping tool is characterized by having an elongated body and a lever arm which is pivoted at one end to the body to actuate a plunger having a chuck and spring-loaded biasing member movable toward and away from a seat on a die portion into which a coaxial cable end can be inserted in facing relation to the biasing member, a plurality of crimpable connectors in succession being loosely assembled on each cable end between the biasing member and seat so that when the lever arm or handle is squeezed toward the body and imparts axial movement to the plunger to force a preassembled crimping ring on each connector to radially compress each connector into sealed engagement with the cable end, the biasing member will compensate for differences in length of said connctors.
Claims23
A hand-held crimping tool for connecting a sleeve portion of each of a plurality of cable fittings to an end of a respective coaxial cable wherein said tool is provided with a body having an end stop at one end of a cable-receiving channel, a plunger axially spaced from said end stop for supporting said sleeve in facing relation to said end stop with said cable end extending through said channel and at least partially inserted into said sleeve, and support means mounting said plunger for axial movement toward and away from said end sop whereby to force a crimping ring on said sleeve axially under sufficient force to radially contract said sleeve into crimpirg engagement with said cable end, the improvement in said tool comprising:
- force-applying means for axially advancing said plunger toward and away from said end stop;
- and
- a resilient biasing member mounted under compression between said plunger and said support means being operative in response to axial advancement of said plunger toward said end stop beyond a maximum distance required for contracting said sleeve into crimping engagement with said cable end for undergoing axial compression when engaged by each of said fittings whereby to compensate for differences in length of said fittings.
A hand-held crimping tool for connecting a sleeve portion of each of a plurality of cable fittings to an end of a respective coaxial cable, said tool comprising a body having an end stop at one end of a cable-receiving channel, a chuck axially spaced from said end stop for supporting said sleeve in facing relation to said end stop with said cable end extending through said channel and at least partially inserted into said sleeve, a plunger mounting said chuck for axial movement toward said end stop whereby to force said sleeve axially into crimping engagement with said cable end, the improvement in said tool comprising:
- a spring-loaded biasing member on said plunger adapted to yieldingly engaging each of said fittings in response to axial advancement of said plunger toward said end stop whereby to cause said sleeve to crimpingly engage said cable end;
- and
- force-applying means for axially advancing said plunger and said chuck toward said end stop.
A hand-held crimping tool adapted for connecting a sleeve portion of each of a plurality of cable fittings to an end of a respective coaxial cable, said tool comprising a body having an end stop at one end of a cable-receiving channel, a chuck axially spaced from said end stop for supporting said sleeve portion in facing relation to said end stop with said cable end extending through said channel and at least partially inserted into said sleeve, a plunger mounting said chuck for axial movement toward and away from said end stop whereby to force a crimping ring on said sleeve axially under sufficient force to radially contract said sleeve into crimping engagement with said cable end, the improvement in said tool comprising:
- an axially compressible, spring-loaded biasing member on said plunger being responsive to axial advancement of said plunger toward said end stop adapted to yieldingly engage each of said fittings;
- and
- a lever arm for axially advancing said plunger toward and away from said end stop.
